Patent & Trademark Resource Center (PTRC)

The Georgia Tech Library has been the Patent & Trademark Resource Center (PTRC) - formerly Patent & Trademark Depository Library (PTDL) since 1946 and we have all available patents issued in the U.S. since 1790 on file together with additional search tools. Though we are not permitted to do any of the application procedures for you nor to give you legal advice, we can help you make your search of the patent and trademark databases more efficient. We can instruct you in the use of the search tools available at the Library for you to conduct your own patent and trademark searches.
